Question

2 NH3 + 3 CuO g 3 Cu + N2 + 3 H2O

In the above equation how many moles of water can be made when 57 moles of NH3 are consumed?

Answer 1

86 moles of H2O.

Step-by-step explanation:

In the reaction 2 moles of NH3 reacts with 3 moles of CuO to produce 3 moles of Cu, 1 mole of N2 and 3 moles of H2O.

So, when 57 moles of NH3 are consumed, the amount of H2O produced will be 3 * 57 moles / 2 moles = 86 moles of H2O.
